# Generate SOURCES in sources.mozbuild files from ICU's Makefile.in
# files, and also build a standalone copy of ICU using its build
# system to generate a new copy of the in-tree ICU data file.
#
# This script expects to be run from `update-icu.sh` after the in-tree
# copy of ICU has been updated.
